1 Claim.

This invention relates to book protectors in reneral, and particularlyto the kind adapted to lot only safeguard the outer, exposed surfaces ofL book, but which will render visible any printed r ornamental matterappearing upon said suraces, or upon any other article interposed beweenthe protector and the book body.

One of the principal objects of the present inention is to provide arelatively sturdy, transarent book protector, which is so constructed .sto permit its ready attachment. to and its emoval from a book, and whichwill facilitate he optional association therewith of an auxiliary IOOkcover, known in the art as jacket. Another object of this invention isto provide book protector, the exterior edges of which are einforced tosafeguard them against excessive wear and tearing, and to hold thestructure of he protector in its intended shape of arrange-' ment.

A still further object of this invention is to rovide a book protectormade of a single elonrated sheet of transparent material, the edgerortions of which are folded upon themselves and .gainst the body of thesheet, so as to provide marginal flaps for the optional reception of aacket, and wherein the folds or ultimate edges, orming the jointsbetween the flaps and body f the sheet, are provided with continuousreinorcing strips, adhesively secured to the folds, .nd extending, to asubstantially uniform width r depth, along the side areas adjacent tothe olds, thus straddling the folds or edges, and by 0 doing maintainingthe flaps in their intended,

olded position.

The foregoing and still further objects and mportant advantages of thepresent invention vill become more fully apparent from the ensuingiescription of the accompanying drawing, the atter showing the presentlypreferred forms of my device, and in which,

Fig. 1 is a perspective view of a portion of my ook protector as appliedto a book;

Fig. 2 is a plan view of one form of my book 'rotector;

Fig. 3 is an enlarged sectional view taken 0 inc 3-4 of Fig. 2;

Fig. 4 illustrates my protector, seen in Fig. 2, :1 a position ofreceiving a book jacket;

Fig. 5 is an enlarged cross-section taken on ine 5-5 of Fig. 4;

Fig. 6 is a perspective fragmental detail view I the flap and itsreinforcement along its fold; .nd

Fig. 7 is a plan view of another embodiment of my device.

Referring now specifically to the figures, and especially to Figures 2and 3, my book protector consists of an elongated strip of preferablytransparent sheet material In, fabricated from any suitable plastic,such as Celluloid. The longitudinal edge portions of the strip are bentor folded upon themselves in the manner indicated in Fig.

3, so as to form distinct flaps l I, the interior surfaces of whichbecome adjacent to the intended interior surface of sheet body I0. Theseadjacent surfaces are normally held parallel to one another. Theultimate edge or fold l2, forming the joint between body l0 and flap H,is straddled by a reinforcing tape or strip l3, which encases the foldsalong their entire length, and overlies uniformly, to a substantiallyeven depth or width, the outer surface areas of flaps H and sheet body10, immediately adjacent to fold l2.

Strip I3 is adhesively secured, and serves not only to reinforce theultimate edges of the book protector, but is designed to hold flaps IIin their intended, folded position. (See Figs. 3 and 6.)

Folds II are intended to removably accommoe date jacket M, in the mannerillustrated in Fig. 4. Such jacket may be provided with attractiveprinting or advertising matter, and since my protector is preferablytransparent such printing is made readily visible.

In inserting the Jacket, folds l are temporarily bent away from bodyill, or are merely lifted, so as to permit jacket I to slip into placewith its outer surface against the inner surface of member Ill. Theassociation of the jacket with my book protector is obviously optional,but the construction of my device facilitates the repeated applicationof my protector to any number of books, and the changing of jackets tomake them correspond with the books to which the device is to beapplied.

While my jacket, is preferably made of transparent material,particularly when intended to be used for holding jackets, it may alsobe made of translucent or opaque material when used merely as bookprotector.

The application of my device to a book will be more clearly understoodfrom consulting Figure 1, wherein the leaf body iii of the book andcovers it and I! are indicated in broken lines. The reinforced edges ofmy protector are intended to coincide with the top (and bottom) edges ofbook covers it and II. The protector is simply applied with its innersurface to the outer surface of the covers, and .wound about theirvertical edges l8, as indicated at 19 in the left-hand portion ofFig. 1. In this manner the folded-over part 20 of the book protectorbecomes adjacent to the interior surface of book cover ll. Jacket I4,held by flap II, is shown to be somewhat longer than my book protector,and its extending end 2| may be folded under, as indicated in Fig. 1.

Referring to Fig. 7, here is illustrated a modified form of my device,which possesses all features explained in connection with the previouslydescribed figures, but in addition is provided with end flaps 22, thefolds of which are reinforced by tapes 23, so that all edges of thefinished articles are reinforced and protected.

The optional insertion of a jacket in this modified form of my device isproceeded with in the manner similar to that'explained in connectionwith Fig. 4, with the exception that the ends of the jacket are slippedunder end flaps 22.

While in the foregoing description ony specific forms of my inventionwere dealt with, it is quite obvious that changes and improvements maybe reiiuired. Thus, reinforcing member l3 may be constructed in adifferent manner and may be placed, for instance, within fold l2. It isalso quite obvious that the fold reinforcement may be constructed from amaterial similar to that from which body I II is fabricated, andalthough I prefer to employ adhesive fabric tape, any other suitablematerial may take its place.

Only two embodiments of my invention are 11- lustrated. They areapplicable to the general run of books handled in circulating libraries,private homes, and the like, where it may be necessary to change orreplace my book protectors or transfer them to books currently used.When, on the other hand, my device is to be employed for permanentlycovering books, periodicals or other publications, suitable changes andimprovements may be required, and I therefore reserve for myself theright to make such changes and improvements without departing from thebroad scope of my invention as defined in the annexed claims.

I claim:

A book covering comprising in combination a substantially transparentmember, and a detachable paper book ;Iacket, said member having a lengthcorresponding substantially to the length of the book Jacket and a widthsufficiently in excess of the width of the book jacket to providemarginal flaps on each side thereof, said flaps being folded over toprovide enclosure means for slidably retaining the paper book Jacketwith the member, and permitting the transparent member and the paperjacket to be applied as a unitary construction to the cover of a book;and means applied to the transparent wrapper for urging the flaps intothe flat folded position against the paper book Jacket carried therein.
